Steven Davis, Cevat Giray Aksoy, Jose Maria Barrero, @nickbloom.bsky.social, Katelyn Cranney, @mathiasdolls.bsky.social, & Pablo Zarate find that both planned and realised fertility are higher among adults who work from home at least one day a week. cepr.org/voxeu/column... #EconSky
The figure reports mean lifetime fertility (realised + planned) by work-from-home (WFH) status. The sample is restricted to respondents aged 20 to 45 who live with a partner. ‘No one WFH’ means neither the respondent nor the partner works from home; ‘Only self WFH’ means only the respondent works from home at least one day per week; and ‘Both WFH’ means both partners work from home at least one day per week.

Fertility has fallen to very low levels in many advanced economies, and many pro-natalist policies appear to deliver modest gains at high cost. Using survey data covering 38 countries, this column shows that both planned and realised fertility are higher among adults who work from home at least one day a week. For couples, fertility is higher still when both partners work from home, indicating that hybrid work may be an overlooked margin for easing the trade-off between family and paid work.

Data from 21 European countries show the progressivity of personal income tax systems gives rise to large tax-to-base elasticities, implying substantial potential for fiscal drag @mathiasdolls.bsky.social, M Freier, @estebangmiralles.bsky.social, A Mazzon, S Riscado cepr.org/voxeu/column... #EconSky
Description of the figure: Comparing actual 2023 revenues against counterfactual scenarios in which the 2019 system had been kept unchanged or fully indexed shows that governments limited fiscal drag to varying degrees.

The 2022 inflationary spike in Europe has brought renewed interest in fiscal drag. Using harmonised microdata for 21 European countries, this column documents that the progressivity of personal income tax systems gives rise to large tax‑to‑base elasticities, implying substantial potential for fiscal drag if parameters are not adjusted. These effects are more prevalent for labour income and for taxpayers at the bottom and middle of the income distribution. Furthermore, it documents very heterogeneous policy responses across countries over 2019–2023, ranging from incomplete offsetting to over‑compensation of potential fiscal drag.

Speaking of debt: Framing, guilt, and economic choices online at @voxeu.org @cepr.org @mathiasdolls.bsky.social @lisawindsteiger.bsky.social cepr.org/voxeu/column...

Speaking of debt: Framing, guilt, and economic choices
In many Germanic languages, the word for ‘debt’ also means ‘guilt’. This column explores whether the linguistic overlap leads to greater debt aversion in Germany, the Netherlands, Sweden, and Switzerland. Using a guilt-laden term reduces willingness to borrow, lowers approval for government debt, and influences firms’ financing plans and politicians’ framing of fiscal policy. While support for public debt goes down with use of the laden term, the effect disappears when the purpose of the debt is clear. Linguistic framing may help guide borrowing toward socially optimal levels.

Was, glaube ich, immer noch nicht richtig verstanden wird bei den #Zoellen von #Trump : Es geht hier gar nicht um Höhe, unfaire Handelspraktiken, etc. Es geht einzig und allein um einen weiteren Versuch (nach der Ukraine), Europa zu schwächen.

Great piece in The Economist covering our latest research on Working from Home. Despite much coverage of return-to-office mandates put out by large firms, work from home arrangements have been stable since 2023. www.economist.com/finance-and-...

Unlike everyone else, Americans and Britons still shun the office
